EECIFICATION forming part of Letters Patent No. 741,443, dated ctober 13, 1903.

Application led June 19,1902.

To a/Z whom it ntfty concern.-

Be it known that I, WILLIAMY HATGHER BASKIN, a citizen of the United States, residing at Mineola, in the county of Lowndes and State of Georgia, have invented certain new and useful Improvements in Cotton-Grins; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in cotton-girls, and possesses among its novel features an improved driving mechanism for operating the various parts of the gin from the main power-shaft and also an improved feeding mechanism designed to effectively regulate the amount of cotton fed to the rolls of the gin within narrow limits.

In order that my said invention may be more readily understood, reference will be had to the accompanying drawings, wherein my said improvements lare shown as embodied in a double-roller cottoivginA constructed in accordance with the improvements covered by Letters Patent of the United States, No. 616,761, granted to me on December 27, 1898.

In the drawings, Figure l is a side elevation of the gin Fig. 2 is an end elevation of the same looking from one end of the machine, the end boards 69, carrying the feed-rolls and their driving-chains, being removed. Fig. 3 is a similar view looking at the same end of the machine, parts of the driving mechanism removed; and Fig. et represents a section taken transversely through the gin, showing the roller-feed mechanism in detail.

In the views, l 2 are the two end frames of the machine connected together by the upper and lower tie-bars 3 4, respectively, bolted or otherwise secured to the end frames. Immediately Within the end frame l is located an A-frame 5, carrying bolts 6, resting in slots 7 in the end frame l, by means of which a horizontal adjustment is provided between said end frame l and the A-frame 5. This frame 5 carries at its upper end a bearing 8, provid ing a suitable journal for the shaft 9. Mounted preferably immediately outside the end frame l upon the same end of the machine is a second A-frame, l0. This frame 10 prefern ably rests upon the floor or other suitable Serial No. 112,367. (No model.)

support or foundation and may be held rmly in place in any desired manner, such as bolt# ing to the end frame 2, relative movement between these frames being necessarily pre; Vented. This frame 10 is provided about mid way of its height with a recess 11, in which rests the journal 12, forming a bearing for the shaft 9. This journal l2 is movable verticallyin this recess and is acted upon by the coiled spring 13, the compressionof which is adjusted through the set-screw 14.

The power-shaft 19 is provided near its outer end with the belt-pulleys l5 16, through which power is supplied to the gin. Inside between the end frames l 10 of the machine is mounted a friction-wheel 17, preferably immediately adjacent the frame 10, which wheel bears resiliently against the frictionwhee1'18 upon the shaft 19. These wheels or pulleys are composed of some suitable mate rial, paper being found suitable for the pur pose. The end of the shaft 19, carrying the friction-wheel 18, is journaled in the bearing 20 in the upper end of the frame 10, the opposite end of the shaft being mounted in the pillow-block 21, carried by the end frame 2.

22 is a pinion securely mounted upon one end of the shaft 9 immediately adjacent the bearing 8 upon the frame 5. Meshing with this pinion 22 is a gear-wheel 23, which in turn meshes with the gear-wheel 24C. These gear-Wheels are preferably of the same size and are mounted upon the inner ends of the stud-shafts 25 26, respectively, each of said shafts being mounted in a bearing 27 28, respectively, hung from the end frame l. Upon the outer ends of these stud-shafts 25 26, respectively, are mounted sprocket-wheels 29 30, respectively.

Mounted upon each end of the shaft 19 is an eccentric 3l at the same angle upon said shaft. Mounted directly above this shaft 19 is a rock-shaft 32, mounted in the bearings 33 in the upper portion of the machine. shaft 32 carries upon each end a yoke 34, in the lower ends of which ride eccentrics 31 upon the shaft 19. Y Double oppositelydis posed arms 35 are carried upon the shaft 32 at spaced intervals, upon the ends of which are carried curved arms 36, the curvature of said blades forming an arc of a circle struck from the shaft 32 as a center. Immediately This Y Ico screws 47 48, respectively.

outside the arms 35are the rollers 37 38, mounted upon the shafts 39 40, respectively, mounted upon the swinging arms 41 42, respectively. These swinging arms 41 42, respectively, are pivotally mounted upon the studs 43 44, respectively, secured to the endframes 1 and 2.

45 46,v respectively, are springs acting upon the shafts 39 40, respectively, carrying said rollers 37 38, the tension of said springs being increased or decreased by means of the set- These rollers 37 38 each carry upon one end of the shaft a sprocket-wheel 49 50, respectively, over which pass chains 51 52, passingover the gear-wheels 29 30, respectively. These rollers 37 38 carry upon their peripheries an elastic covering 53 54, respectively, such as very thick leather or other suitable material, either grooved or otherwise, as may be desired.

Journaled in the end frame 1 2, directly over the rock-shaft 32, is a rotating shaft 55, carrying near each end thereof an eccentric 56. Upon this eccentric 56 are mounted double arms 57, preferably diverging downwardly. Upon each end of these diverging arms are pivoted brackets 58, each secured to the longitudinally-disposed feeding-boards 59, each resting upon the inclined slotted plates 60, constituting seed-grates. These seed-gratos extend from one end of the machine tothe other in front of the rollers 37 38 and have their outer ends in close proximity thereto. These feeding-boards 59 slide back and forth upon the upper side of these seed-grates 60 through the action of the eccentrics 56 upon the shaft 55.

Upon the upper extension 6l of the end frames of the gin are recesses 62, within which are located the bars 63, carrying upon their 'lower ends the knife-blades 64, bearing` upon the elastic covering of the rollers 37 38, respectively. 'Fliese blades are so shaped and disposed as to be clear of the path of the curved oscillating blades 36 upon the rockerarms 35, and said blades may be adjusted as desired by means of the bolts 66', acting upon the bars 63, carrying said blades.

Mounted directly above the feeding-boards 59 are the feeding-rollers 66 67, respectively, each provided upon its periphery with spirally-arranged teeth or spikes 68. These rollers 66 67 are preferably mounted at each end inthe end pieces 69, closely fitting upon the top of the machine between the extensions 6l 61, the same being so secured as to allow the parts to be readily lifted out, together with the feeder-rollers 66 67. The feed-rollers 66 67 revolve in the same direction as the rollers 37 and 38 and`in close proximity to the periphery of the rollers 37 38 and cooperate with the feeder-boards 59, working back and forth upon the seed-grates 60. These feed-rollers may be driven through 'sprockets 70 7l, respectively, connected to the sprocket-wheels 72 73, respectively, upon the shafts 39 40, respectively, through the chains 74.75. The shaft 55 may be similarly driven through the sprocket-wheel 76, connected to a sprocket-wheel upon one of the shafts of the feed-rollers through the chain 77.

The operation of the gin is as follows: Power is applied to the power-shaft 19 from any suitable source. The friction-wheel 18, carried by the shaft 19, will impart motion to the friction-wheel 17 upon the shaft 9, causing the same to rotate. This will cause the eccentrics 3l, carried upon each end of said shaft 19, to rock or oscillate the rock-shaft 32 through the yokes 34. On the other end of the shaft 9 the pinion 22 will impart its motion to the gear-wheel 23, which in turn imparts itsmotion to the gear-wheel 24, these gears 23 24 revolving in opposite directions. These gears through their respective shafts impart motion to the sprockets 29 30, respectively, which in turn transmit power to the rollers 37 38 through the chains 51 52, respectively, said rollers revolving in the direction indicated by the arrows, Fig. 4. Connected to sprocket-wheels 72 73, respectively, upon the shafts 39 40 of the rollers 37 38, respectively, through the chains 74 75, respectively, are sprockets 7l, connected to the feed-rollers 66 67, respectively, said feed-rollers being thereby caused to revolve in the same direction with the rollers 37 38, respectively, as indicated by the arrows in Fig. 4. The sprocket-Wheel76 upon the eccentricshaft 55 is preferably connected to a sprocket uponone of the roller-shafts, such as by a sprocketchain 77. This motion thus imparted will cause the double arms 58, riding upon the eccentrics 56, to reciprocate the feeding-boards 59 back and forth over the slotted seed-grates 60, while the rocking motion imparted to the rock-shaft 32 will cause the double arms 35, carrying the curved blades, to oscillate between said feed-boards 59 and the rollers 37 38, said blades working in close proximity to the elastic covering upon said rollers and said blades 64. Cotton may 110W be fed into the gin between the end pieces 69 and over the feeding-rollers 66 67. These rollers 66 67, carrying spikes 63, will feed the cotton between the rollers 37 38 and the reciprocating boards 59. These boards 59 move the cotton, ordinarily containing much seed, back and forth over the slotted seed-grates 60 60, also pressing the cotton against the rollers, causing the seed to become separated from the cotton and to disappear through said grate, where they may be collected in any desired manner. In the meantime the curved blades 36, acting in close proximity to the periphery of the rollers 37 38, Will feed the cotton thus freed from seed up beneath the knife-blades 64 64 and assisted by the rotation of the rollers 37 38 will be carried over the same, the cotton being stripped therefrom in any suitable well-known manner. These knife-blades are adjusted through the set-screws 65 and 66 to be in such proximity to the surface of the rollers 37 38 that the cotton will be drawn therebetween in very small quantities, seeds and other enlargements or obstructions being excluded. However, should an uneven quantity of cottonV pass between the knifeblades 64 and the rollers 37 38 said rollers will yield through the resilient pressure of the springs 4.5 46, allowing the same to pass said knives. The fact that the feed-rollers 66 67 are located in the position shown in Fig. 4 allows the amount of cotton fed to the rollers 37 38 to be regulated within very narrow limits, as the excess of cotton is automatically returned to the bin formed upon the top of the gin by these feed-rollers o6 G7. Thus it will be seen that a feeding device is provided whereby cotton is brought forward to the working point before the rollers when needed and the surplus is automatically returned, an excess of cotton at the working point retarding the operation of the machine.

I have shown my invention as embodied in but one form of machine; but it will be understood that I do not so limit myself, and while my invention is especially designed as an improvement upon my former Letters Patent aforesaid it will be understood my improvements are applicable to the various forms of gins now in common use, and while I have employed certain details of construction in the embodiment of my invention herein shown and described it is obvious that many changes 'and modifications may be made therein, which changes and modifications could be made without departing from the spirit of my said invention.
